United Airlines Pet Policy
United accepts small dogs and cats in the cabin on most US domestic flights for a $125 fee each way. The carrier must fit entirely under the seat and the pet must remain inside for the duration of the flight. United PetSafe is the cargo program for larger animals, but breed restrictions apply, especially for brachycephalic breeds.
